What is the principle involved in froth flotation? Complete answer: We can discuss the principle behind the froth flotation process as the basic principle of the froth flotation process is that the ore containing the impurities and the mineral are crushed into fine powder and mixed with water.The hydrophilic impurities stay in the liquid phase with the water.
